Valuable Features:* Easy to setup* Easy to maintain* Great support* You can use any SIP phone or softphonesImprovements to My Organization:It saved us a lot of money when we switched from a hosted solution to Barracuda on-premises.Room for Improvement:It needs High Availability.Deployment Issues:There were some issues in our UK office because dialing abroad from there is different to dialing abroad from the US, but tech support customized the settings for us.Stability Issues:No issues encountered.Initial Setup:It couldn't be easier.Cost and Licensing Advice:It's cheaper when compared to other phone systems.Other Solutions Considered:* iCore - hosted solution - too pricey* ShoreTel - a lot of different pieces of hardware needed* Mitel - great phone solution but expensive and you are locked into using their phones* Asterisk - complex setup and maintenanceDisclaimer: I am a real user, and this review is based on my own experience and opinions.
